no evidence that they cause autism. None whatsoever. There is a weak chance that they can cause the disease that they are made from or some weakned version of it.

I find that autism is a curious subject. I find it to often be a word that has just taken the place of "mentally retarded" since that's not PC anymore. I wonder if anyone has compared medical notes from say, 40 years ago to those now and compared what the doctors observed to get both diagnoses.

Live, attenuated vaccines can potentially cause the disease they're meant to protect. One example is that the oral polio vaccine occasionally caused the polio virus. Others can cause virus symptoms: the chicken pox vaccine can occasionally cause a person to have a mild pox appear, and become contagious during that time.
